Other Location Info
The project site consists of two parcels containing a commercial building and a two-story office building. The existing commercial building at the corner of Mathilda and Olive was constructed in 1976 as an office building, used as a financial institution and since 2007 as a retail store; it is approximately 7,201 square feet in size. The two-story office building on Olive was constructed in 1961 and provides multi-tenant small office spaces; it is 13,543 square feet. Together, the two buildings total 20,744 square feet. There have only been minor permits issued for either site and/or building maintenance. There is minimal existing landscaping on either property; mature trees are located on the Olive (south) side of the older building.
Other Information
The parcels are located in Block 13 of the DSP and the two parcels are designated with a total of 47,660 square feet of office and 5,683 square feet of commercial space. The DSP was amended in August of 2020 which included changes that allowed proposed development to exceed the designated square footages through Community Benefits and a Development Agreement. The proposed project includes demolition of the existing structures and the construction of a new 125,128 square foot, four-story mass timber office building with two levels of underground parking. The exterior of the building will be cladded with a glass curtain system on three sides of the building with extruded bay window elements used to add interest on the façades. The east façade, which faces single-family homes, would also have a curtain wall with wood cladding and smaller window openings. The pedestrian entrance would be located at the corner of S. Mathilda Avenue and W. Olive Avenue and would be enhanced with an exposed exterior stairwell and vertical supports for an arbor element above the fourth floor. Vehicle access to the underground parking garage would be via a driveway located on W. Olive Avenue. The rooftop would include open space for tenants of the building, landscaping, covered arbor area and space for mechanical equipment. The site would be landscaped and would include new sidewalks, driveway access, and other plantings
